That's definitely a big upside. Things like dishes and laundry are great background tasks. Doesn't take long to set up, then a machine handles the rest, swap out the laundry and keep going. Barely interrupts my day job, and the impetus to get out of my chair is welcome anyway.
Boss makes a dollar, I make a dime. That's why I poop on company time...Love to have someone else clean up the empty bathrooms at work every day or so; shame that job was almost two hours away for the 2 days a week I had to go.
I can settle for a public bathroom, but surely we have the technology to construct walls without significant gaps. Spend the one-time extra investment so that I can pretend I have some privacy.
One of the most underrated features of WFH is my own private bathroom. This is something I would never have at the office.
